“…Atropine blocks the action of both drugs, but is without effect on vagal stimulation. Eserine by itself is without effect, but causes strong contractions along with acetylcholine (Aikawa, 193 I ; Barrington, 1942; Carlson & Luckhardt, 1921;Dixon, 1902; Epstein, 1931Eura, 1927;Fiihner, 1918; Gellhorn & Budde, 1923; Yuh, 1931-3). In the same animals most observers have recorded that adrenaline reduces the tone and inhibits automatic contractions of oesophagus and stomach (Carlson & Luckhardt, 1921; Epstein, 1931Epstein, , 1932aEura, 1927; Gellhorn & Budde, 1923; Yuh, 1931-3).…”
